This format is derived from the xcsv
format, so it has all of the same options as that format.

Tab separated export-all (except geocaching data) file
format. Intended to serve as source for number-processing
applications like OpenOffice, Ploticus and others. Tab was chosen as
delimiter because it is a) supported by both OpenOffice and Ploticus
and b) is not ',', so you can use sed -i
"s/./,/g" <x>.csv' to adapt it to locales where ',' is
used as decimal seperator. Contributed by Tobias Minich.
